I am getting the error you can see in the title above.
This is the command which I ran:
factanal(~numofdoors+wheelbase+length+width+height+curb_weight+numofcylinders+enginesize+horsepower+peakrpm+price, factors=3, rotation="varimax", scores="none", data="CarStandard")
Can someone tell me how I can fix this issue?
